"But knowing that Marouane played 90 minutes at the weekend is good to know, it means that he is getting very close to being fully fit and if he is needed he will always be available to the national team.

"The two medical departments had very good conversations and the best decision is the one we took. There's been nothing strange about the situation of Marouane.

"It's good to see he got through the 90 minutes. We are delighted he is getting [back] to his best level, the same way that we were disappointed he couldn't participate with us in the previous camp because of the niggles.

"That was a disappointment we shared with his club. We are working all together, this is not a war [with Manchester United], this is not a situation where we are trying to get revenge over anyone."

Another United star, Romelu Lukaku, will be rested for Thursday's friendly with Iceland as he continues his recovery from a hamstring strain.

But Martinez could use the striker against Switzerland as Belgium look to reach the Nations League Finals.

"Romelu will train today with the group," added Martinez. "He's had a very positive reaction so we'll take it day by day, see how he feels and we'll take it [him playing] into consideration."
